Solar power solutions


Betta144 is a robust external area and security solar lighting solution.


  • Security gates, external parking areas, dark areas not on the grid, Government buildings for rural areas such as clinics, schools and border posts, perimeter fencing.
  • Light Distribution: Betta144 uses 120 LED diodes and has a light distribution angle of 140 degrees. Illumination is 20 lux at 5 meters on the centreline. As a result the demonstrated area coverage per light is approximately 200-300sqm with a distance of 20 meters.
  • Lead Crystal batteries: The system makes use of 2 x 22Ah 12Volt lead crystal batteries. These batteries can handle heat of up to 65 degrees C, it can be depleted 100% and will take charge thereafter, it recharge 2 to 5 times quicker than other lead acid battery  technologies with a life expectancy of 10 years.
  • Bracket: The Betta144 can be mounted on a 5-6 meter galvanized pole with a 76mm or 115mm thickness on the top or on a wooden pole with a thickness of 155mm on top. The bracket system is available in stainless steel or mild steel and is e-coated and poweder coated against any form of corrosion.

The Betta144 can be configured with either one or two light heads per pole installation. The size of the solar panel will depend on the area of installation due to the weather and climate influence.
